FX-6 was used during the extensive repairs to General Grievous after a horrible shuttle crash. During Darth Vader's reconstruction, the same FX-6 unit performed numerous blood tranfusions, and stabilized terrible damage done to Vader's lungs, eyes, vocal cords, scalp, face, arms, and legs. This FX-6 was damaged by Darth Vader after the Dark Lord was told he had killed his wife. However, the droid appeared to be functional when Vader's Force blast ceased.
